T0 all whom it may concern.-

Be it known that I, I-IoNEsTUs M. ALBEE, a citizen of the United States,residing at Newark, in the county of Essex and State of New Jersey, haveinvented certain new and useful Improvements in Vtoodworking Machines;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same,referencebeinghadtotheaccompanying drawings, and to letters and figures of referencemarked thereon,which form a part of this specification.

r1"his invention relates to certain improvements in that class ofmachines for cutting or carving spiral grooves in the peripheralsurfaces of wooden sticks, illustrated in my United States Patent No.408,366.

For this present invention, subsequent to the filing of the applicationbut before the issuing of this patent, l have received patents inforeign countries as follows: England, No. 13,864, dated August 17,1891; Belgium, No. 96,103, dated August 31, 1891; France, No. 215,601,dated December 4, 1891; Germany, No, 62,889, dated June 14, 1892, andCanada, No. 41,789, dated February 2, 1893.

,i The objects of the present improvements are to facilitate theoperation of cutting reverse spirals, to secure greater perfection inthe work, to provide against vibration when turning spirals on sticksofcomparatively large size and to secure other advantages and results,some of which will be set forth in connection with the description ofthe working parts. The invention consists in the improved wood workingmachine and in the combinations of parts thereof substantially as willbe hereinafter set forth and finally embodied in the clauses of theclaim.

Referring to the accompanying drawings, in which like letters andfigures indicate corresponding parts in each of the several views,Figure 1 is a plan of the machine. Fig. 2 is an end view and Fig. 3 arear view of certain reversing mechanisms, and Fig. 4, a detail showingmore clearly the construction and arrangement of a certain carriage.Fig. 5 is a detail side view of a stick holder, rest or support.

In said drawings, a, Fig. 1, indicates a suitable fixture or support fora bracket, b, carrying pivotal bearings, c, for a vibrating arm d. Saidarm consists of pivoted sections d', d2, d3, and, at the outer end ofthe section, d3, a vertically adjustable section, el, which lastprovides bearings for a rotary shaft, e. Said shaft carries a rotarycarving or routing tool e. At the joints in the sectional arm, and onthe rotary tool shaft, are pulleys f', f2, f3, and f4 and these areconnected by belts, g', g2, g3, g4, with any suitable motor or source ofpower, so that rotary motion will be imparted to the shaft, c, and toolcarried there, by, all as will be understood.

Below the plane of movement of the vibrating arm and its tool, on asuitable table or support, h, is arranged a lathe, between the centers,c' and j, of which, the wooden piece to be turned and ornamented with aspiral or other desirable ornamentation may be arranged, and back ofsaid centers is a screw shaft, lc, which is geared to the shaft j', ofthe center j, by a train of gearing 7a2, k3, kt, clr, shown moreclearlyin Fig. 2, by means of which the screw shaft and the center, j,and the wooden piece carried thereby, are caused to turn simultaneouslyat proportional rates of speed, the movement of the screw shaftgoverning the movement of the wooden piece worked upon, as will beunderstood.

On the screw shaft is arranged a carriage, lt', which slideslongitudinally upon the plate, h', of the table, its movement beinginduced by the rotation of the screw shaft. To this carriage is attachedthe vibrating arm and rotary carving tool by means of a bar, la, thesaid tool being held thereby in a position to engage the turning stickor wooden piece. By turning the hand wheel, m, on the screw shaft,(power being applied to the rotary carving tool) the stick is caused torevolve slowly with the center, j, and the carriage, it', is forced tomove longitudinally, carrying the carving tool on the jointed arm withit and, as a result, a-spiral groove` is cut in the stick. It frequentlyhappens, however, in ornamunicatereverse movement 'to the `wheel 76.4

, extension7611.

mental wood work, that two sets of spirals are desired, pitched inopposite directions, the oppositely pitched grooves being in one and thesame stick, giving a diaper effect to the ornamentation or the saidoppositely pitched grooves being in separate pieces.

To secure a reversely pitched eut quickly and accurately, is one of theimportant features of the present improvement. To this end, I providemeans for reversing the direction of pivotal' movement of the stick inits relation to the screw shaft. This is accomplished by means of avibratory frame or plate 769, Figs. 2 and 3, pivoted or centered on theshaft, 76, and having, at suitable points thereon, gear wheels 763, 767,adapted to engage with the Wheel, 764,0f the train of gearing and bedisengaged therefrom alternately, as will be understood. The wheel, 763,receives its powerdirectly from the gear wheels, 762, on theshaft, 76,while the wheel, 767, receivesl its power from thev said wheel, 762,mediately or through the intermediate gear wheel, 768, so that itsmovement will be in a reverse direc.- tion fronrthe .,wheel, 763, andwill thus comand lthe wooden piece geared thereto. The adjustable frameor plate, 769, is held in either of thetwo positions of operation, bymeans of aset screw, 7610, which werks in a slotted ,t In connectionwith the lathe center'j, I have provided a gage disk, p, which .turns onthe same pivotal shaft with said center and the gearorcog wheel 766 asshown onlyin Fig. l. The periphery of said disk is divided off by Iequi-distant graduations, say six, eight or ten,

dividing the periphery into sixths, eighthsor tenths, or the saidperiphery, may be, and preferably is, divided cireumferentially asshown, one of the subdivisions having six graduations enabling theworkman to readily make six cuts or grooves at proper distances apart onthe stick, the second subdivision havingeight and the third tengraduations as willl be ,readily understood.

Adjacent to, the graduated or marked periphery of theV disk, @,is afixed or stationary index, q. This is preferably secured upon the box orbearing r, for the shaft referred to` in Iconnectionwith the center j.

, By means of the gage arranged as described, the 'longitudinal' orspiral grooves-may be quickly and accurately spaced on the stick. Inoperating this device, the first groove may bestarted on the periphery,the index. coincidingrwith an initial graduation of eitherone oftheseries desired. As the stickrevolves and the spiral groove is being eut,the disk alsorevolves and when the next graduation lniark arrives atthe` index, the tool may be lraised out of the first spiral groove andbrought again to the end of the stick and a second groove started at aproper point regulatedby the index and this maybe continued until thestick has the requisite number of 'properly spacedgrooves.

lplate 3.

In the prior device, above referred to, it may be observed that a stickholder is provided, consisting of jaws adjustable in relation to oneanother by means of adjusting screws and movable with the carriage. Sucha device is desirable more particularly and especiallyin connection withvery small work of a certain class requiring bearing close to therouting tool. For larger work, I have provided a holder or rest s, shownmore clearly in Fig. 5, consisting of a V-shaped head t, so that theround and either ,parallel sided or tapered stick will have two bearingsin the holder at opposite sides of a longitudinal and vertical centralplane through the stick. The said head has aleg, u., which is adjustably secured to an adjustable stud, o, arranged on the bed or plate,7a', ofthe table, being'V held thereon by vset screws, t" adapted toadmit of a ready changeof position in accordance with the necessities ofthe work. Thus the V-shaped head maybe raised or lowered, adjustedlongitudinallyv with respect` to the Q stick and changed in angle tocorrespond, for example,

with a taper inl a baluster. v z

To enable either large or small sticks to be l operated uponand toregulate .the depth of the groove` in the stick, without changing thegear wheels and centers of thelathe, yand to secure peculiar effects incarving in vaccordance with a desired pattern, I havemade the carving orrouting toolvertically adjustable in `its bearings, the adjustment beingcontrolled by a guide rod, w, and tracing tool,

w', adj ustably arranged on lsaid rod, and the latter being attached toavertically sliding plate which controls the vertical movement o f thetool shaft, as described particularly, in

a cotemporaneous specification or in any other suitable manner. Byraising or lower- `ing the pattern, 4, orby varying the upper bearingsurface of said pattern, giving the same a waved surface for example,the-depth `of the spiral groove will be correspondingly varied. If thework to be operated upon be very large and beyond the limits of verticaladjustment of the tool shaft, then I may lower theytable, 71 in anysuitableV manner, (the jmeans for doing so not being shown, the samebeing old,) to admit of the introduction of the said large work to theVcenters. To do this and yet secure the proper connection and support ofthe vibrating arm with the carriage, 76, and bed plate 7L', I have madethe connections vertically adj ustableas shown in the drawings, whereh2, indicates an elevated track at the rear of the plate7t, on which thesaid carriage slides horizontally when forced by the screw shaft 76. y t

7612 indicates a vertically slotted arm of said carriage; 7620 a clam padapted toreceive a bar or extension, 7613, of a plate, 7611, whichcontrols the movement of the vibrating arm and `furnishes a bearing forthe vertically sliding When vthe table, h, is to be lowered, the clamp,762,0, is first loosened totadmit of the lowering of the table and latheandl after- IIO ward the parts 7612 702 7513 are again brought intorigid connection by the nut 7050.
